You should definitely go into a new orbit that intersects your old orbit at two places. Assume you start in a circular orbit. If I understand correctly, since a jump towards the Earth (or away from the Earth) doesn't change your angular momentum, the latus rectum of the orbit doesn't change, so you will intersect the original orbit 180 degrees around. That's slightly less than half the orbital period, because that's how elliptical orbits work -- faster near periapsis, slower near apoapsis.
